ColdTrace puts you inside a real investigation, or at least, it feels that way. Navigate a stranger's phone, piece together the timeline, and decide: was it really an accident?
AN IMMERSIVE FICTIONAL EXPERIENCE
• Explore a fully simulated phone interface: messages, photos, notes, voicemails
• Uncover a layered narrative where every clue matters
• Multiple threads to follow, one truth to uncover
FEEL THE TENSION
The line between player and investigator blurs. You're not watching the story unfold, you're living it. Every deleted file, every text thread, every timestamp brings you closer to the answer.
YOUR INVESTIGATION, YOUR PACE
ColdTrace is not a passive experience. What you read, what you dig into, and when, it all shapes your understanding of what happened.
For fans of interactive fiction, true crime podcasts, and crime documentaries who want to go deeper.
ColdTrace is a fictional narrative experience. All characters and events are entirely invented.
Note: Some chapters require a Premium unlock.
Some investigations are available for free, while the complete experience can be unlocked through an in-app purchase.
